I've been trying an experiment using an Smartsteem promoting system. I'd tried 5 posts and every post I've invest different value.
It's results.
• how much SBD was spent on investing = 15.234
• how much SBD was earnt (clear profit) = 2.376
• what is the average cost of promoting for one post in SBD = 3.047
• what is the average income for a post in SBD = 0.475
what is the average of profit 15.6%
And it's clarified that I earned a cleared profit by 15.6% of my investment. Thanks for
